One-Round Protocol for Two-Party Verifier-Based Password-Authenticated Key Exchange
Password-authenticated key exchange (PAKE) for two-party allows a client and a server communicating over a public network to share a session key using a human-memorable password only. PAKE protocols can be served as basic building blocks for constructing secure, complex, and higher-level protocols which were initially built upon the Transport Layer Security (TLS) protocol. In this paper, we pro...
متن کاملVerifier-Based Password-Authenticated Key Exchange: New Models and Constructions
While password-authenticated key exchange (or PAKE) protocols have been deeply studied, a server corruption remains the main threat, with many concrete cases nowadays. Verifier-based PAKE (or VPAKE) protocols, initially called Augmented-PAKE, have been proposed to limit the impact of any leakage. However, no satisfactory security model has ever been proposed to quantify the actual security of a...
متن کاملPassword-Authenticated Multi-Party Key Exchange with Different Passwords
Password-authenticated key exchange (PAKE) allows two or multiple parties to share a session key using a human-memorable password only. PAKE has been applied in various environments, especially in the “clientserver” model of remotely accessed systems. Designing a secure PAKE scheme has been a challenging task because of the low entropy of password space and newly recognized attacks in the emerg...
متن کاملEfficient verifier-based password-authenticated key exchange in the three-party setting
In the last few years, researchers have extensively studied the password-authenticated key exchange (PAKE) in the three-party setting. The fundamental security goal of PAKE is security against dictionary attacks. The protocols for verifier-based PAKE are additionally required to be secure against server compromise. Some verifier-based PAKE schemes in the three-party setting have been suggested ...
متن کاملProvably Secure Threshold Password-Authenticated Key Exchange
We present two protocols for threshold password authenticated key exchange. In this model for password authentication, the password is not stored in a single authenticating server but rather shared among a set of n servers so that an adversary can learn the password only by breaking into t+ 1 of them. The protocols require n > 3t servers to work. The goal is to protect the password against hack...
